' I coNoRErn-romu nEvIoE;

To all whom it may concern:

Be it known that I, ANTONIO CoLAR sso, a citizen of the United States, and resident of Hudson, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Concrete- Form Devices, of which the following is a specification.

My invention relates to improvements in concrete form devices and more particularly to devices serving as a form for the edges of concrete roadways, although it may be found useful in many other situations, including the building of sidewalks, etc.

The main object of the invention is to provide an arrangement which is notonly'simple and inexpensive, but which may be easily and quickly put in place and adjusted to the desired positionand which will remain firmly in place as long as desired and: is then easily removed for further operations.

Further and more specific. obj ects, features and advantages will more clearly] appear from-the detailed descriptionvgivenbelow, taken inconnection withethe accompanying 1 j drawings which form apart of this speci-' fication.. The drawing, Figure '1, is an end view of a device embodyingthe invention in one form. Fig. 2 is the verticalsectionof a concrete roadway showing the invention in one form in use. Fig. 3is aside view of theform shown in Fig. 2. Fig. i is aside view of the stake forming part of the deivice shown in'Fig. 1. a Fig. 5 is an edge view of the hook or supporting member, a side view of which is shown in Fig 1. Fig. 6 is a detail of the screw threaded member for holding the parts together; and Fig. 7 is a perspective. of the nut which locks or holds the parts. firmly. with relation to one Referring to the various figures, 1 represents a stake, preferably an iron rod tapered at the lower end, so that it may be easily driven into the ground; 2 represents a' hook-shaped member adapted to pass around the'lower edge of a' plank form, 3, and upwardly on both sides "of said plank form; irepresents a screw threaded member which passes loosely through a'hole, 5, in the stake 1, the hole 5 not :beingthreaded. The screw threaded membert also passes through a hole 6, in the-hook shaped" member 2, thehole 6 being screw threaded to operatively engage the screw, threads on the member a; 7 represents a nut operating s eoifiseon fmer ia iien Patented cause, an.

on the screw threads of the member ion the other sides-0f the stakel." Ihe screw threaded-member 4 may bc bent' at its outer end as shown in the drawings to form a loop, so that it may be easily turned by inserting through the loop abarwhich will serve' as a handle. The vertical face'of' the plank 3 serves as the formfor the concretezat the edge of the roadway, sidewalk or the like.

Inloperation, the stakes are driven into the ground at the points desired, either with or without the hook members 2, screw threaded members 4 andnutslin place. Afterthe hook-shaped members 2 and screw threaded members 4 and nuts 7 are-put in place, as illustrated in Fig. 2, the plank forms 3; are then deposited in the hook-shaped supporting members 2. The plank members are-then lifted to the desired: height and the screw threaded memberst operated until itsinner end firmly engages the plankform 3, so that the latter is held firmly in place at the desired height, it being preferableto have the top of the-plank form13come even with the top of the conoreteroadway T-he parts are so'arrangedthat thetop of the plank form I 3 is as high as'or higher than the other parts of the device, so that 'templets or screeds' may-be used on top of the plank form 3 without interferencefrom the other parts ofthe arrangement; I i

It will beseen from the' abovez-that-the device will hold the plank forms without the use of nails and is thus economical, both in the saving ofnails and the preservation of planks. The arrangement also prevents the saggingof the plank forms, a common occurrence when such forms are .nailed'to wooden-stakes; The device allows the engineer; to set his iron-stakes with his instru ment and the plankforms may then be adgrade adjusted position," that is, if the'stake is' driven a little too low. so that with the plank 3' resting upon the bottom of thehook shaped member2, the plankform would be too low, the plank form may be raised-and held in the desired raised position by oper-,

engages the plank 3 and secures it in the desired position. The nut 7" may' then be tightened up in order to bind the, members 1, 2 and 4; firmly together.

.Although I have described my improvements in'detail with regard to one particular embodiment thereof, Ldo not. desire to be limited to such details, as many changes and modifications mayv be nmde Without. de parting. from the spirit and scope of. my invention in its, broader aspects and what I,- claim as new and desire to secure. by Letters Patent is:

1-. A concrete form device comprising'a' stake, a hook member adapted to support' a vertical: concrete form with the top of: the

form above the. top of the .hook member-,"a

screw. threaded member passing. laterally through the-stake and operating, laterally through the hook. member and adapted to engage the form to hold it. firmly in ad justed. position and a nut; cooperating; with the screw threaded member? and stake=to bind the, stake, hook member and, screw threaded member rigidly together- 2. A concrete form device comprising; a stake,- a hookmember adapted to; support-Eavertical concrete form, a screw threaded member passing laterally through the stake and operating laterally through the hook member and adaptedto engage the formato hold it. firmly in adjusted position. and; a nut coiiperating. with the: screw threaded; member and stake to bind the stake, hook member and. screw threaded member rigidly together.
